The above link will help you decide if you belong to BC (Backward
class) community. Further ,BC is classified into creamy layer and non creamy
layer. If you belong to Non creamy layer ,then you belong to OBC.

What
is Creamy layer ?

The termcreamy
layerwas first coined by Justice Krishna Iyer in 1975 in State of Kerala vs
NM Thomas case, wherein he observed that the benefits of reservation are
snatched away by the top creamy layer of the 'backward' caste or class, thus
keeping the weakest among the weak always weak.

They are not eligible for
government sponsored benefits in education and employment.

In UPSC, there are separate cutoffs for the General category
and OBC category .The cutoff of
the OBC category is slightly lower than the General Cutoff.

The candidates
belonging to creamy layer are taken under “General Category’

Please Note -The creamy layer is only applicable in the case
of Other Backward Castes and not applicable on other group like SC or ST.

Who belongs to Creamy layer ?

For children of persons in civil services, please note that the below
list belongs to creamy layer

Important Note –

If you belong to creamy layer because of the
above conditions ,you will continue to fall in creamy layer even after your
parents retire from service.

.YOUR INCOME/STATUS DOES NOT MATTER.Creamy layer is based on the status of your
parents and has nothing to do with your income/status nor the status/income
of your spouse.

.Eligibility
regardinggovernment employee is based upon his level, and not his salary.
Example –If your parents are earning 7 lakhs and they are below group B
officers ,you will still come under ‘NON CREAMY LAYER.’

For children of PUBLIC SECTOR UNDERTAKINGS/PRIVATE SECTOR

If you are not able to establish
equivalence vis-à-vis government jobs,then

Compute the income of your
parents from salaries and income from other sources separately.(Income from
other sources excludes salaries and agricultural land)

Income from Salaries(FOR 3 CONSECUTIVE

·The term “Isostasy” is
derived from “Isostasios”, a word of Greek language meaning the state of being in balance.

·You already know and must
have seen that the mountain have many peaks and relatively great heights.

·Similarly plateau and plain
have flat surfaces. They have moderate and lower height, respectively.

·On the contrary oceanic beds
and trenches have greater depths. There is a great difference in height among
these features.

·You also know that the earth
is rotating while keeping perfect balance among its various features.

·Thus, our earth is considered
to be in isostatic equilibrium.

·Example:- Suppose you are
holding one stick each in your both hands vertically with varying heights, say
5’ and 15’ and you are moving in a particular direction.

·Do you have any difficulty in
maintaining a balance in congruence with your body as well as two sticks
together? Definitely, smaller stick will be easy to make a balance than the
longer one. It is just because of the centre of gravity.

·The centre of gravity with
smaller stick will be nearer to your holding hand in comparasion to the longer
stick. In the same way smaller surface features like plains are more
stable than the tall mountains.

A. Isosatic Balance: views of Airy

·Airy, a geologist, considered
the density of different columns (plains, plateaus, mountains, etc.) to be the
same. Hence, he proposed the idea of ‘uniformdensity with
varying thickness’.

·We know that the upper crust
of the earth is made up of lighter material. In this layer, silica and
aluminium are found in abundance, hence it is known as ‘Sial’.

·It is less denser than the
lower one. Airy assumed that the Sialic crust is floating over the Sima (silica
and magnesium, lower denser layer).

·Crustal layer is uniform in
terms of density with varying length of columns. Therefore, those columns are
projecting down into the asthenosphere depending upon the proportions of the
column.

·It is due to this reason
that the root has developed or the sima has been displaced from below.

·To prove this concept, Airy
took an example of wooden blocks of various sizes and immersed them into water .

·All blocks are of same
density. They get immersed differently in proportion to their sizes.

·In the same way higher
features with great height seen on the surface of the earth have deeper roots
whereas short in length has shorter roots beneath.

·It is the concept of root
which is sustaining the higher elevation. He is of the openion that the
landmasses are floating like a boat in the substratum (magmatic asthenosphere).

·According to this concept,
the root beneath the Mt. Everest would be 8848X8 = 70784 metre below the sea
level.

·On this bases Airy has been
criticized that the root is not possible to be at such a great depth. Because
the root material will melt due to higher temperature found at that depth.

B. Isostatic Balance: views of Pratt

·Pratt considered land blocks
of various heights to be different in terms of their density.

·The taller landmass has
lesser density and smaller height features to be denser. In other words, there
is an inverse relationship between height and density.

·If there is a higher column,
density will be lesser and if there is a shorter column, density will be
higher.

·Assuming this to be true,
he accepted that all blocks of different height get compensated at a certain
depth into the substratum.

·In this way a line is being
demarcated above which there is equal pressure with varying heights.

·Thus, he denounced the root
concept of Airy and accepted the ‘concept of a
level of compensation’.

·For proving his concept he
took a number of metal bars of varying density with same weight and put them
into mercury .

·In this way they form a line
by all those bars, which he regarded to be the level of compensation.

Differences between the views of Airy and Pratt :

Compensation.

C. Global Isostatic Adjustment :

·It is quite apparent that there
is no complete isostatic balance over the globe. The earth is unstable.

·Endogenetic forces often
disturb the crustal balance.

·The regular earthquakes and
volcanic eruptions along a particular belt do not signify any balance but a
sort of adjustment is needed continuously.

·Endogenetic forces and their
tectonic effects are the causes of imbalance on the surface but nature always
tries to make an isostatic adjustment with itself.

·Exogenetic forces are trying
to eliminate the differences on the surface of the earth and in this process
they are peeling off, transporting down to far flung places, and depositing
them.

·In this process, isostatic
balance is maintained by the underneath flowage of material by subsidence at
the place of deposition and upliftment at the peeling of place in their
proportion to the denudation ..
